Abstract

La présente invention concerne des rotors cylindriques à équilibrage automatique permettant de fragmenter des matériaux tels que de la biomasse et un terrain. Les rotors peuvent comprendre deux ensembles de mécanismes d'équilibrage vers chaque extrémité du rotor cylindrique. Chaque mécanisme d'équilibrage comprend un canal circulaire. Des éléments d'équilibrage dans chaque canal circulaire peuvent être répartis à travers le canal de sorte à équilibrer le rotor. Les éléments d'équilibrage peuvent comprendre un dispositif de verrouillage qui est réglable entre un état verrouillé dans lequel les éléments d'équilibrage ne peuvent pas se déplacer dans les canaux circulaires, et un état déverrouillé dans lequel les éléments d'équilibrage peuvent se déplacer dans le canal circulaire.
